Radiologic Studies for Malignant Otitis Externa: A Systematic Review and Meta-Analysis

37 studies on Necrotizing Otitis Externa (NOE) were analyzed to determine the diagnostic accuracy of radiologic studies. The work was conducted by Do Hyun Kim of The Catholic University of Korea Seoul St. Mary's Hospital. It reports sensitivity values for gallium-67, technetium-99m, MRI, and CT scans under different diagnostic criteria.

Use Cases

• Compare diagnostic sensitivity of different imaging modalities (gallium-67, technetium-99m, MRI, CT) based on the reported meta-analysis results.
• Evaluate the impact of diagnostic criteria (e.g., bony erosion alone vs. with soft tissue abnormality) on CT scan sensitivity for NOE.
• Inform clinical guideline development for imaging in suspected malignant otitis externa based on aggregated evidence from 37 studies.

Strengths

• Methodological quality was evaluated using the standardized QUADAS-2 tool.
• Provides specific sensitivity estimates with confidence intervals for four imaging modalities.
• Analysis is based on a systematic review of 37 individual studies.

Limitations

• Row count and column-level documentation for the underlying study data are unknown.
• The dataset represents aggregated meta-analysis results, not raw patient-level imaging data.
• Last update date is unknown; freshness unverified.
